but pretty much you need a 360x180 pano
where you try and keep the camera in the same spot
(this might be a lot depending on how wide your widest lens is)
then you stitch them into a pano - can use hugin for this but i used my normal pano software
then you stitch it into a little planet using hugin
(its harder than what it sounds lol)
